Polaroid SX-70 SONAR OneStep. Product of 1978.

The reason of calling the Polaroid instant camera “Land Camera” is because of the inventor Edwin Land. He manufactured different series of instant self-developing film cameras between 1947 and 1983.

The older version of Land Cameras (e.g. Series 100 to 400 pack film camera) produce a lot of wastes – the peeled negative side, the number tabs, the pulling tabs etc…, making the cameras not so convenient to use.

SX-70 solved this problem by using another type of instant film. It is a folding single lens reflex (SLR) camera takes integral instant film from 1972. The version we introduced here is the FIRST auto-focus SLR in the world, by using the ultrasonic system called SONAR. So, it has a long name called Polaroid SX-70 Land Camera SONAR OneStep.
